SanDisk Extreme Portable SSD 2TB Allocation Unit Size
I've bought this highly-regarded SanDisk Extreme Portable SSD 2TB to use as general backup and storage for my MacBook Pro. I have a good mix of smaller documents and larger media files with an increasing need to accommodate larger (12-20gb) video projects. I have received much conflicting information regarding the default file unit allocation size on this SSD. SanDisk chat support now tells me it is 4096 bytes and cannot be altered by Mac OS, only in Windows. Other forums say it is 1mb by default and can be changed in Mac OS, however with no directions given. I was advised to use ExFat since I must often share collaborative projects with Windows users. I'm no expert and my MacBook's disc utility does not display any allocation unit info. Can anyone advise: 1) if this SSD allocation unit size can be determined and changed in current Mac OS? 2) if so, how or what utility to use? and 3) what unit size might be optimal/suggested for the described purposes?
Many thanks in advance from this relative newbie to a great support community.
